Blynk Time input - lost connection to app


#1

I’m new with arduino but I have have made a fish feed machine running a sequence of opening a door first and then running a snail and then closing it again.

I can start it with a push button and with a time input from the blynk app.
It seems fine, but once it has run the first loop of the sequence.

The connection is lost and continues to write
[177810] Connecting to blynk-cloud.com:8442 in the serial monitor.

Is there anyone who has encountered that problem?

My code is here.

Only those that don’t read thoroughly, can’t code properly, is having networking issues, possibly power issues… oh and even the “experts” will get that occasionally as well :wink: So basically everyone :stuck_out_tongue: Yes, it is a common error saying something is preventing proper connection between your MCU and the server.

And since you can run it the first time, then it sounds like you have flooded or timed out the heartbeat.

But without more details and posting your properly formatted code (see Welcome Topic - and we don’t want to use your links) as well as doing some reading of the Documentation and Help Center (Links all at the top of this page) and of course, searching this forum for this common issue and answers (are you running everything in the void loop() or using timers - correct answer is NO and YES :wink: )

http://docs.blynk.cc/#troubleshooting

Post your formatted code here and we will see what we can do to assist.

No I’m not a good reader nor a good programmer :slight_smile:
I also think it’s flodded, but I can not see what the problem is.
If I dont run the loop. It does not lose the connection.

I’m not sure if I’m doing right when I transfer from the DS3231 RTC module to the app, but I’ve seen myself blind and can not fix it

Well you don’t have to be a good programmer… but you DO need to be a good reader :stuck_out_tongue:

Paste your code here… properly formatted as recommended above.
